Introduction

When elemental mercury is spilled, it forms beads or droplets that canaccumulate in the smallest of places. These beads or droplets can emitdangerous vapors that are odorless & colorless in air. It is this vapor that posesa serious hazard to anyone within close proximity to a mercury spill or release.

Mercury has been found in Egyptian tombs dating back to 1500 or 1600 B.C. Asearly as A.D. 23-79 mercury was know to be dangerous, and it was not until A.D.500-700 that mercury was considered a metal. In the 1800’s the term “mad as ahatter” was coined. This term described the physical symptoms of mercurypoisoning that hat makers experienced from having their hands immersed in vatsas they shaped felt hats.

Mercury is the only metal that remains in a liquid state at room temperature, thehigher the temperature, the more vapor is released. The vapor pressure ofmercury will double when the temperature increases from approximately 64.4 Fto 78.98 F.

In this guidance document, no distinction is made between home,school, or industrial settings during a spill or release. Appropriateclean up methods and safety considerations are vital for eachsetting. Throughout this document, the clean-up levels will bedistinguished for each setting.

It is the experience of many in the environmental field that most mercury spillsare preventable. Special recognition is given to the Ohio Mercury ReductionGroup (ORMG), chaired by Ohio EPA for educating the public and sponsoringmany programs to remove mercury from homes, medical facilities, schools,industry and other places where mercury is used and a suitable replacement areavailable. Additionally, the Ohio Mercury Reduction Group educates the publicon the dangers of mercury through direct means as well as outreach programs.

Special recognition is also given to Bowling Green State University (BGSU) for itssponsorship of the Ohio Mercury Reduction Program. BGSU and its partnersprovide for the safe transportation and reclamation of elemental mercury andmercury-containing devices throughout Ohio at no charge.

The information contained herein was obtained from a number of sources and isbelieved to be the most accurate and up-to-date information on mercury, itsbehavior, its hazards and cleanup methods. Several trade names are used inthis document, however OSPPERA does not endorse, recommend or warrantthese products. They are used only as examples of products that may beavailable for use in the cleanup of a mercury spill or release.

Mercury Reduction and Spill Planning & Prevention

Every effort should be made to prevent a mercury spill from occurring due to thehealth effects of mercury vapor, the cost associated with the clean-up and thedifficulty in removing mercury vapor from certain areas. The best way to preventa release of elemental mercury is not to have it! Proper disposal or reclamationof the mercury is strongly recommended. If you must keep mercury-containingdevices, please follow these precautionary measures

• Always store mercury in unbreakable container.• Store in well-ventilated area.• When using mercury-containing devices, do so over plastic containment

tray. Make sure container is of sufficient size to contain the greatestamount of mercury that may be spilled.

• Transfers of mercury should be done under an appropriate exhaust hoodand over a plastic containment tray. Make sure container is of sufficientsize to contain the greatest amount of mercury that may be spilled.

• Maintain an appropriate spill kit in area where mercury is used or stored.Know and follow all manufacturer directions.

• Whenever possible, choose non-mercury containing devices.• If you use fluorescent lights, remember they are considered universal

waste and should be managed as such (40 CFR 273). (Note: Citizensare exempt.)

• Work surfaces should have few crevices and carpeted areas should neverbe used.

• Appropriate training is required for anyone working with or cleaning up amercury spill.

• Have written spill plan for mercury releases, practice and update often.

Defining Mercury Spill Size & Suggested Definitions

Spill Size

Small Spill (Contained): A spill that may result from a broken thermometer orthermostat. The amount of mercury contained inthese devices is usually around 3 grams.

Small Spill (Spread out): A spill that may result from a broken thermometer orthermostat. This spill has spread out either by thebeads of mercury breaking apart upon impact withanother surface or by tracking either by humans oranimals. This spill usually is confined to one roomand the impacted area may cover up to 50 squarefeet.

Large Spill: A spill from any source of mercury that involvesmultiple rooms, buildings, motor vehicles or where theimpacted area covers more than 50 square feet.

Suggested Definitions

Clean Area: Where mercury vapor is demonstrated to maintainedbelow 1 µg/m3 for no less than 4 consecutive hoursfollowing adequate and appropriate decontaminationprocedures. (ATSDR Residential Occupancy Level)

Restricted Area: Where mercury vapor levels exceed 1 µg/m3 but lessthan 10 µg/m3. An approved APR with mercury vaporcartridges should be worn in these areas.

Controlled Area: Where mercury vapor levels exceed 10 µg/m3. Anapproved SCBA should be worn in these areas.

Types, Sources and Properties of Mercury

Metallic Mercury (Elemental Mercury)• Shiny, silver-white metal that exists as a liquid at room temperature.• Expands and contracts evenly with temperature changes.• Highly toxic.• Readily vaporizes at or near 55°F.• Reaches gaseous state at 300°C.• Alloys with copper, silver, nickel, gold and zinc to form amalgam.• Bioaccumulates in humans, animals and the environment.• Found in thermometers, barometers, thermostats, pressure gauges,

dental offices, blood pressure devices, fluorescent light bulbs and sometennis shoes that light up.

• Very high level of electrical conductivity (but has no charge), used inbatteries, rectifiers, oscillators, power control switches and vapor lamps.

• Is not water-soluble.• Used in the production of chlorine gas (amalgamates with sodium in

sodium chloride), caustic soda and gold extraction.• Used in the production of paint• Medicinals: Used primarily in dental offices for cavity filling.• Herbal and religious remedies in Latin America, Asia and Caribbean. Sold

under the name “Azogue”.• Vapor can accumulate in wall spaces, attics, etc.• Vapor can accumulate in electronic equipment, especially computers.

Mercury re-vaporizes when device is turned on and heat is generated.

Health Effects

Very high exposures to mercury vapor can cause acute poisoning and/or death.Symptoms usually begin with cough, chest tightness, difficulty breathing andupset stomach.

Acute inhalation of mercury vapor may result in chills, nausea, general malaise,tightness in the chest, chest pain, difficulty breathing, cough, kidney damage,stomatitis, gingivitis, salivation, diarrhea and death.

Mercury is considered a poison and the routes of exposure include inhalation,ingestion and absorption. The most common route of exposure for elementalmercury is inhalation. The most common route for of exposure for organicmercury is ingestion.

Mercury has a delayed burning sensation to the skin and eye of several minutesup to several hours.

The central nervous system is very sensitive to mercury vapor. Chronicexposure is characterized by behavior changes, weakness, fatigue, weight loss,gastro-intestinal dysfunction, tremors in fingers, eyelids and lips, memory loss,insomnia and depression.

Medical Monitoring

Taken from OSHA Technical Link, Occupation Safety and Health Guideline forMercury Vapor, Revision Date: 27 April 1999.

MEDICAL SURVEILLANCE

OSHA is currently developing requirements for medical surveillance. When theserequirements are promulgated, readers should refer to them for additionalinformation and to determine whether employers whose employees are exposedto mercury vapor are required to implement medical surveillance procedures.

* Medical Screening

Workers who may be exposed to chemical hazards should be monitored in asystematic program of medical surveillance that is intended to preventoccupational injury and disease. The program should include education ofemployers and workers about work-related hazards, early detection of adversehealth effects, and referral of workers for diagnosis and treatment. Theoccurrence of disease or other work-related adverse health effects should promptimmediate evaluation of primary preventive measures (e.g., industrial hygienemonitoring, engineering controls, and personal protective equipment). A medicalsurveillance program is intended to supplement, not replace such measures. Todetect and control work-related health effects, medical evaluations should beperformed (1) before job placement, (2) periodically during the term ofemployment, and (3) at the time of job transfer or termination.

* Pre-placement medical evaluation

Before a worker is placed in a job with a potential for exposure to mercury vapor,a licensed health care professional should evaluate and document the worker'sbaseline health status with thorough medical, environmental, and occupationalhistories, a physical examination, and physiologic and laboratory testsappropriate for the anticipated occupational risks. These should concentrate onthe function and integrity of the eyes, skin, respiratory system, central andperipheral nervous systems, and kidneys. Medical surveillance for respiratorydisease should be conducted using the principles and methods recommended bythe American Thoracic Society. A pre-placement medical evaluation isrecommended to assess medical conditions that may be aggravated or mayresult in increased risk when a worker is exposed to mercury vapor at or belowthe prescribed exposure limit. The health care professional should consider theprobable frequency, intensity, and duration of exposure as well as the nature anddegree of any applicable medical condition. Such conditions (which should notbe regarded as absolute contraindications to job placement) include a history andother findings consistent with diseases of the eyes, skin, respiratory system,central and peripheral nervous systems, or kidneys.

* Periodic medical evaluations

Occupational health interviews and physical examinations should be performedat regular intervals during the employment period, as mandated by any

12

applicable Federal, State, or local standard. Where no standard exists and thehazard is minimal, evaluations should be conducted every 3 to 5 years or asfrequently as recommended by an experienced occupational health physician.Additional examinations may be necessary if a worker develops symptomsattributable to mercury vapor exposure. The interviews, examinations, andmedical screening tests should focus on identifying the adverse effects ofmercury vapor on the eyes, skin, respiratory system, central and peripheralnervous systems, or kidneys. Current health status should be compared with thebaseline health status of the individual worker or with expected values for asuitable reference population.

* Termination medical evaluations

The medical, environmental, and occupational history interviews, the physicalexamination, and selected physiologic or laboratory tests that were conducted atthe time of placement should be repeated at the time of job transfer ortermination to determine the worker's medical status at the end of his or heremployment. Any changes in the worker's health status should be compared withthose expected for a suitable reference population.

* Biological monitoring

Biological monitoring involves sampling and analyzing body tissues or fluids toprovide an index of exposure to a toxic substance or metabolite. No biologicalmonitoring test acceptable for routine use has yet been developed for mercuryvapor. However, total inorganic mercury can be measured in the urine by preshiftsampling. A mercury level of 35 micrograms per gram of creatinine should beused as the biological exposure index. In addition, total inorganic mercury canalso be measured in the blood by sampling at the end of shift at the end of theworkweek. A mercury level of 15 micrograms per liter of blood should be used asthe biological exposure index.

Taken from CPL 2-2.6 OSHA Instruction October 30, 1978, OSHA ProgramDirective #300-2, Inorganic Mercury and Its Compounds

MEDICAL SURVEILLANCE

Each employer should institute a medical surveillance program for all employeeswho are or will be exposed to airborne concentrations of mercury vapor or thedust of its inorganic compounds above the permissible exposure limit. Theprogram should provide each employee with an opportunity for biologicalmonitoring and medical examination performed by or under the supervision of alicensed physician and provided during the employee's normal working hourswithout cost to the employee.

Medical Examinationa. Each employer should provide a medical examination which includes a

complete medical history and physical examination, complete blood count,routine urinalysis (specific gravity, sugar, protein determinations, andmicroscopic examination), and voluntary pregnancy test, whereappropriate, to each employee exposed to mercury or its inorganiccompounds in excess of the permissible exposure limit.

b. Medical examinations should also be made available: i. To employees prior to their assignment to areas in which

airborne concentrations of mercury or its inorganiccompounds are above the permissible exposure limit;

ii. At least annually for each employee exposed to airborneconcentrations of mercury or its inorganic compounds abovethe permissible exposure limit at any time during thepreceding six months;

iii. For each employee whose urine analysis sampling seriesindicates elemental mercury level at or above 0.02 mg perliter of urine or total mercury level in excess of .200 mg perliter of urine, which is not receding;

iv. Immediately upon notification by the employee that theemployee has developed signs or symptoms commonlyassociated with toxic exposure to inorganic mercury or itscompounds.

c. Where medical examinations are performed, the employer should providethe examining physician with the following information:

i. The reason for the medical examination requested; ii. A description of the affected employee's duties as they relate

to the employee's exposure; iii. A description of any personal protective equipment used or

to be used; iv. The results of the employee's exposure measurements, if

available; v. The employee's anticipated or estimated exposure level; vi. The results of the employee's biological monitoring; and

14

vii. Upon request of the physician, information concerningprevious medical examination of the affected employee.

Biological Monitoring

Urine sampling and analysis should be the biological monitoring method used.The method of analysis for total, ionic and elemental mercury in urine isdescribed in the American Industrial Hygiene Association Journal, September1974, pp. 576-580. For the analysis at least 100 ml of urine should be collectedduring a workday when sampling is scheduled.

Accuracy of Measurement. Sample analysis should have an accuracy to aconfidence level of 95% as it pertains to the repeatability of several analysesfrom any given urine sample.

Frequency of Monitoring (a) If possible, a urine sample should be obtained of allemployees who will be assigned to work with mercury or its inorganic compoundsprior to exposure to the work area. (b) For employees exposed to less thanpermissible levels of airborne mercury, urine sampling and analysis should bedone every six months. (c) For employees exposed to airborne mercury vapor orinorganic mercury compounds above the permissible exposure limit, urinesampling and analysis should be performed every three months for eachemployee. It should continue at least six months after the last known exposureabove the permissible exposure limit if the employee is available for sampling. (d)Where the total mercury level exceeds .200 mg of mercury per liter of urine, or0.02 mg of elemental mercury per liter of urine, sampling should be acceleratedto a weekly basis. The activities of the employees should be observed to detectthe potential source of mercury intake. (e) If the total mercury level in urine doesnot decrease during the one-month sampling period, or if the elemental mercurylevel in urine does not decrease in two weeks, a physician should be consulted.The results of employee urine sampling should also be considered as a groupexposure by area of assignment and/or by job description. Elevated group urinemercury levels should be a cause for review of operational practices, processcontrols, and a change in either or both to reduce employee exposures. If severalemployee urine samples from the same area of assignment indicate excessiveelemental mercury urine levels, the employer should start corrective action in thearea immediately.

Physician's Written Opinion

The employer should obtain and furnish the employee with a written opinion fromthe examining physician containing the following: (a) The signs or symptoms ofmercury exposure manifested by the employee, if any; (b) A laboratory report ofthe mercury content in blood or urine if such analysis is performed by or underthe supervision of the physician, or reported to the physician by a laboratory towhich such samples have been submitted for analysis; (c) The physician's

15

opinion as to whether the employee has any detected risk of material impairmentto the employee's health from exposure to mercury or its inorganic compounds orwould directly or indirectly aggravate any detected medical condition; (d) Anyrecommended limitation upon the employee's exposure to mercury or itsinorganic compounds or upon the use of personal protective equipment andrespirators; and (e) A statement that the employee has been informed by thephysician of any medical condition which requires further examination ortreatment. (ii) The written opinion obtained by the employer should not revealspecific findings or diagnoses unrelated to occupational exposure to mercury orits inorganic compounds. (iii) If the employer determines, on the basis of thephysician's written opinion, that any employee's health would be materiallyimpaired by maintaining the existing exposure to mercury or its inorganiccompounds, the employer should place specific limitations, based on thephysician's written opinion, on the employee's continued exposure to mercury orits inorganic compounds.

DO NOT USE APR when concentrations of mercury vapor areimmediately dangerous to life and health, are unknown, or when theconcentration exceeds 10 times the PEL with half-face respirators or 50 times thePEL with full-face respirators.

Special Notice on Coveralls and other PPE

It has been reported that cotton and nylon clothing will absorb mercury vapor soit is important that all exterior clothing (PPE) be of an appropriate material suchas Tyvek® or equivalent. Coveralls should be manufactured with hoods andelastic wrist and ankle openings.

20

Mercury Spill, Initial Actions

When notified of a mercury spill or release, the following information should begiven to the individual reporting the incident. The health and safety of individualsexposed or potentially exposed is the first priority when a mercury spill occurs.Performing the following activities will help to reduce the danger posed bymercury vapors at the time of a release. Once all individuals have evacuated anarea of mercury release, re-entry should not be permitted without appropriatepersonal protective equipment (PPE) and personnel training.

1. Evacuate immediate area and do not allow pregnant women, smallchildren or pets to enter area. Individuals within the spill zoneshould remove shoes prior to exiting the area.

2. Do not attempt to vacuum spilled mercury without approvedmercury specific vacuum.

3. If mercury came in contact with clothing, including shoes, removeand place in plastic bag and seal. Place plastic bag containingcontaminated clothing out of doors and downwind.

4. If mercury came in contact with exposed skin, immediately washexposed areas with warm water and mild detergent.

5. Open window to out of doors if mercury was spilled in an area withan outside window.

6. Turn off HVAC and/or other ventilation to and from impacted area.7. If possible, place towels or other impervious material on floor to

stop vapors from exiting under doorways. Place duct tape alongdoor edges to contain vapor.

8. Notify Ohio EPA at 800-282-9378.Notify Local Health Department (See OSPPERA Directory).Notify Spill contractor experienced in mercury spill remediation(See OSPPERA Directory).Notify others as appropriate.

9. If possible, unplug and place all computers and monitors into trashbags and seal with tape. Do not remove from area.

10. DO NOT RE-ENTER AREA.11. If school or other public location, identify one person to coordinate

and manage incident with regulatory agencies, parents, media,response contractor and other who may be impacted by theincident.

12. Identify potentially exposed individuals.13. Identify possible satellite spill locations (school buses, other rooms,

homes, automobiles, etc. Isolate as needed.

21

Removal of Mercury from Hard Surfaces(Concrete, tile, porcelain, metal, plastic) (Excluding Wood)

1. Remove all jewelry, including eyeglasses prior to donning PPE andentering spill area. Also, be sure all exposed metal objects such aspens, pagers, cellular phones, blue jean rivets, work boot grommetsetc. are removed or covered by PPE prior to entering spill area.

2. Physically remove all visible mercury using approved mercuryspecific vacuum. Exercise care while vacuuming to ensure allareas are vacuumed, paying particular attention to joints betweentiles. Mark each vacuumed square with piece of duct or maskingtape to show vacuuming has been completed. If elemental mercuryis visible, plastic coated playing cards, duct tape, shaving cream orother items may be used to recover the mercury prior tovacuuming.

3. Wash impacted area with mercury vapor suppression solution.4. With area secured (windows sealed, HVAC isolated, etc.) heat area

to at least 85o F for four (4) hours.5. After four (4) hours of heating area, open doors and/or windows

and ventilate to outside for at least one (1) hour. Utilize blowersand/or ventilation fans to facilitate air movement throughout entirearea.

6. During ventilation, thoroughly mop floors with clean, clear hotwater. Change bucket out as water temperature cools or waterappears dirty.

7. Allow entire area to dry as ventilation continues.8. Thoroughly vacuum entire area with approved mercury specific

vacuum as ventilation continues. Exercise care while vacuuming toensure all areas are vacuumed, paying particular attention to jointsbetween tiles. Mark each vacuumed square with piece of duct ormasking tape to show vacuuming has been completed.

9. Monitor vapor concentrations with mercury vapor analyzer. Vaporlevels should be below 10 µg/m3. Covering the area with plasticsheet and creating “head-space” prior to monitoring vaporconcentrations may also be used.

10. Repeat all the above if mercury vapor levels exceed 10 µg/m3 afterone (1) hour of ventilation to out of doors.

11. After performing 1-10 above, high levels of mercury vapor may stillbe detected. Apply (with brush) two (2) coats of a clear finish, fastdrying polyurethane lacquer to affected surface.

14. Once polyurethane is applied and cured, verify mercury vaporconcentration is below 10 µg/m3.

22

Removal of Mercury from Carpeted Surfaces and Wood Floors

1. Remove all jewelry, including eyeglasses prior to donning PPE andentering spill area. Also, be sure all exposed metal objects such aspens, pagers, cellular phones, blue jean rivets, work boot grommetsetc. are removed or covered by PPE prior to entering spill area.

2. Physically remove all visible mercury using approved mercuryspecific vacuum. Exercise care while vacuuming to ensure allareas are vacuumed, paying particular attention to joints betweencarpeting and molding. Be sure to vacuum both with and againstthe carpeting nap so ensure miniscule mercury beads are removedfrom the carpeting. For wooden floors, pay particular attention tojoints between flooring sections. Mark each vacuumed square withpiece of duct or masking tape to show vacuuming has beencompleted.

3. Wash impacted areas with mercury vapor suppression solution.4. With area secured (windows sealed, HVAC isolated, etc.) heat area

to at least 85o F for two (2) hours.5. After two (2) hours of heating area, open doors and/or windows and

ventilate to outside for at least one (1) hour. Utilize blowers and/orventilation fans to facilitate air movement throughout entire area.

6. Repeat 1-5 above.7. Allow entire area to dry as ventilation continues.8. Thoroughly vacuum entire area with approved mercury specific

vacuum as ventilation continues. Exercise care while vacuuming toensure all areas are vacuumed, paying particular attention to jointsbetween carpeting and molding. Be sure to vacuum both with andagainst the carpeting nap to ensure all amalgam and residualMercury is removed from the carpeting. For wooden floors, payparticular attention to joints between flooring sections. Mark eachvacuumed square with piece of duct or masking tape to showvacuuming has been completed.

9. Monitor vapor concentrations with mercury vapor analyzer. Vaporlevels should be below 10 µg/m3. Covering the area with plasticsheet and creating “head-space” prior to monitoring vaporconcentrations may also be used.

10. Repeat all the above if mercury vapor levels exceed 10 µg/m3 afterone (1) hour of ventilation to out of doors.

11. If, after one (1) hour of ventilating the area to outside the mercuryvapor concentration still exceeds 10 µg/m3, the carpeting orwooden flooring should be removed, along with any padding orsub-flooring under the carpeting and/or wooden flooring. Once thecarpeting/pad and/or wooden flooring/sub-floor are removed, theprocedures for removing mercury from hard surfaces should beused.

23

Removal of Mercury from Contaminated Furnishings and/orClothing

1. Wrap and seal contaminated items in plastic sheeting or place intoplastic trash bags or drum liners.

2. Set up disposable structure (tent) to hold contaminated personalbelongings and furnishings downwind of work area and of otherstructures.

3. Place several industrial or shop grade electric, gas or kerosenepowered heaters inside tent and place blowers at exhaust points insidetent.

4. Post at least one (1) ten-pound fire extinguisher outside of structureand smoke/fire detector inside of structure.

5. Maintain temperature inside structure at no less than 85o F.6. Place contaminated items inside structure, segregated by source

and/or level of contamination.7. Heat contaminated items in the structure to force the vaporization and

removal of mercury for at least two (2) or three (3) days. Longerheating periods may be required for heavily contaminated furnishingsand clothing.

8. No person should enter this “decontamination structure” unless trainedand protected with a minimum of OSHA Level C protection.

9. Clothing or furnishings such as draperies may be heated andventilated using a commercial clothes dryer set to the highest heatsetting. Cycle items at least twice before screening and cycle the dryerempty and on the highest heat setting between batches ofcontaminated clothing and/or furnishings.

10. All clothing and furnishings should be screened using a mercury vaporanalyzer. If mercury vapor readings consistently exceed 10 µg/m3,disposal of the items should occur.

11. Appropriate decontamination and disposal of all materials andsupplies, including the actual decontamination of the structure shouldoccur prior to dismantling the structure.

Option: Wash clothing in commercial or household washing machinesubstituting the detergent with a mercury vapor suppressant. Wash inlongest cycle, using hot water. Dry clothing on hottest heat setting.See above protocol if mercury vapor reading exceed 10 µg/m3.Clothing may be placed in a sunny, warm and open-air area tofacilitate vaporization of mercury from clothing. Exercise care whenchoosing such a site to protect downwind exposure.

24

Removal of Mercury in Plumbing

Mercury in plumbing is usually contained in the traps adjacent to the plumbingfixture such as sinks, drains and toilets. Dismantling is the preferred method ofrecovering the elemental mercury from the plumbing in this setting. Once themercury is recovered from the drains, the mercury vapor concentration should beobtained using a mercury vapor analyzer. For concentrations exceeding1000mg/m³, refer to the Removal of Mercury from Hard Surfaces protocol.

If dismantling of the plumbing is not possible or practical, a magnetic amalgampowder may be used. The magnetic amalgam powder can be gently poured intothe plumbing fixture containing the mercury and gently forced into the trap by useof drain plunger. This technique should be employed with extreme caution so asto avoid forcing the mercury farther into the plumbing system. Wait severalminutes, allowing the magnetic amalgam powder to react with the mercury, andintroduce a plastic covered magnet into the plumbing system. Removal of themercury is achieved by slowly withdrawing the plastic covered magnet.

25

Removal of Mercury from Humans and Animals

Humans1. Issue trash bag or drum liner to each individual contaminated.2. Remove shoes and place into bag and seal.3. Provide disposable shoe covers to person to allow them to walk to

showering facilities.4. Once at showering facilities, have exposed individual remove all

clothing and jewelry and place into trash bag or drum liner and seal.Provide receipt to individual for items recovered describing whatwas placed into bag (include color, size, etc. and other identifyingmarks). Use separate bag for jewelry items. Assure privacy for allindividuals.

5. The exposed individual should then shower, including the washingof hair in warm water using mildly alkaline soap. A commercialproduct such as HgX7 Hand Cream and Cleaner may also be used.

6. Once showered, each individual should be screened using amercury vapor analyzer. Levels of mercury vapor should be lessthan 1 µg/m3.

7. Individuals should be issued a Tyvek® coverall and shoe coversfollowing showering and clearance of mercury vapor.

8. Individual clothing and jewelry should be assessed using theMercury Removal from Contaminated Furnishings and/or Clothingprotocol.

Animals1. Issue trash bag or drum liner for each animal contaminated.2. Remove collar or other items from the animal and place into bag

and seal.3. The exposed animal should be showered in warm water using

mildly alkaline soap. A commercial product such as HgX7 HandCream and Cleaner may also be used.

4. Once showered, each animal should be screened using a mercuryvapor analyzer. Levels of Mercury vapor should be less than 1µg/m3.

5. The collar and/or other items removed from the animal should beassessed using the Mercury Removal from ContaminatedFurnishings and/or Clothing protocol.

26

Removal of Mercury from Soils

In most cases, mercury contamination is close to the surface. An investigationshould be conducted to determine the quantity of mercury spilled and whether ornot surface and/or ground waters have been impacted. For contaminated soils,excavation to 50% beyond the depth of contamination is required to ensureremoval of the contaminant. The contaminated soils can be placed into DOTapproved 55-gallon drums or other suitable containers for off site disposal at afacility licensed to treat and/or dispose of the waste.

The only published standards for soil clean up levels are found in the VoluntaryAction Plan (VAP) published by Ohio EPA. Although mercury spills are not VAPcleanups, these levels are provided as reference only.

Residential land use: 16 mg/kg 3745-300-08(c) (OAC)Commercial land use: 250 mg/kg 3745-300-08(d) (OAC)Industrial land use: 230 mg/kg 3745-300-08(e) (OAC)

Miscellaneous Mercury Removal Guidelines

AppliancesScreen washer and dryer.Remove and ventilate any clothing.If appliances screen <10 µg/m3, run on high heat setting for multiplecycles.

Vacuum CleanersScreen and assess each component of vacuum (hoses, bags, etc.).Remove any porous material.Decontaminate non-porous sections (see above protocol) or dispose.

28

General Clean-up Guidelines

§ Wash all impacted areas with mercury vapor suppression solution.§ Screen all appliances§ Allow for appropriate reaction time for mercury vapor suppression solution to

work.§ Rinse all areas with clean, clear water and change often.§ Re-screen for mercury vapor as appropriate.§ Isolate non-impacted areas prior to ventilation.§ Utilize cross ventilation in impacted areas using high velocity fans; vent into

area from non-impacted areas and out of doors. Vent to out of doors§ Allow at least 24 hours for appropriate ventilation§ Screen both impacted and non-impacted areas to measure effect of

decontamination.§ If screening is above action levels, a mercury source likely still exists.§ If screening is below action levels, consider heat/ventilate cycles.§ If screening is well below action levels, sampling may be conducted.§ Seal off impacted areas prior to sampling§ Increase room temperature§ Allow impacted area to stabilize over 4 – 6 hours prior to sampling.§ Collect samples from 3 – 4 feet above floor (breathing zone for children).

NIOSH Method 6009 or equivalent (8 hour).§ Maintain records of screening location(s) and changes over time; along with

any activity(s) that may have occurred to cause such as change.§ Often, it is helpful to grid an area off in 1 foot by 1-foot squares. Use string or

tape to mark the grid. As vacuuming and/or decontamination occur, a pieceof tape may be used to show the grid square has beenvacuumed/decontaminated.

Directions for the Reduction of Mercury Vapor using HgX77Used with Permission

For use on all surfaces exposed to Metallic Mercury-Mercury Salts-or containingMercury in any form. HgX7 is particularly recommended for rough surfaces, suchas worn concrete floors, having cracks or crevices-wooden floors with openjoints, etc.

Directions (Dry Method)Distribute 8 oz. Of HgX7 powder even over 100-sq. ft. of floor area to be treated.Brush or sweep HgX7 lightly into all cracks and crevices, then spray, sprinkle orswab with water.

Directions (Wet Method)For the initial treatment add 1½ pounds of HgX7 slowly or sift to 5 gallons ofwater – do not dump. Following applications may be reduced to 1 pound foreach 5 gallons of water. HgX7 solutions should be milky – if clear increasequantity. Apply with a sprayer, large whitewash brush, or mop – saturatedwooden floors thoroughly – allow standing over night, preferably over holidays orweekends. Rinse mop or sponge with clear water to remove residual HgX7 ifnecessary.

We suggest washing or generous spraying of all floors and wall surfaces everytwo weeks in operating areas with HgX7 with will provide a coating or film onMetallic Mercury or reduce to non-vaporizing form. HgX7 will also react withvarious Mercury compounds and materially reduce Mercury contaminated airfrom such sources.

For regular sweeping we suggest saturating ordinary sawdust with HgX7 solutionas described herein, you will reduce the dust hazard and treat the area at thesame time.

Directions (Closed System)To decontaminate closed systems which cannot be treated practically by the wetmethod outlined above, fill the system with HgX7 solution (1½ pounds in 5

38

gallons of water) and agitate or circulate the solution for several hours. Drop thesolution and flush thoroughly with clear water. Repeat if necessary.

NoticeIf the HgX7 is caked or lumpy, due to storage, simply remove the entire plasticbag and roll the bag and its contents on a flat surface or simply squeeze by handuntil powdered.

Due to the variations in the water supply in certain areas the quantity of HgX7may require some adjustment. If the water, after adding the recommendedquantity of HgX7, does not turn milky (white) within 15 minutes or half hour, addadditional HgX7 until it does. The solution upon standing several hours(overnight) will turn clear but retain if efficiency. The precipitation on the bottomof the container is merely the excess above saturation.

CautionBe sure to properly ventilate all areas suspected of Mercury contamination.Continue adequate ventilation during decontamination procedures until Mercuryvapor concentration is lowered to acceptable levels. HgX7 Powder and HgX7solution may cause corrosion to some metals. Clean all treated metal surfaceswith clear water and dry thoroughly.

Avoid contact with eyes, skin or clothing. Use rubber gloves. Do not mix HgX7with other cleaning agents or any other material. Use cold tap water to make upsolutions.

ELEMENTAL MERCURY COLLECTION AND RECLAMATION PROGRAMAdapted from www.bgsu.edu/offices/envhs/environmental_health/mercury/program.htm

Used with Permission

The elemental mercury collection and reclamation program began as a formalprogram in January 1998. The program was established following the report ofyoung children who had contaminated themselves and several buildings withelemental mercury. Participants in the program include Bowling Green StateUniversity, Ohio EPA District Offices (Division of Emergency and RemedialResponse), Rader Environmental Services, OSPPERA and ToledoEnvironmental Services. The Wood County Emergency Management Agencyand the Wood County Health Department have also assisted in this effort.

The program involves the collection of uncontaminated elemental mercury from avariety of sources. These sources include thermometers, manometers,barometers, sphygmomanometers (blood pressure measurement devices),mercury-containing heating thermostats, mercury switches, as well as individualcontainers of elemental mercury. The program is available and FREE toindividuals, academic institutions, small businesses, industries, medical anddental facilities, emergency response and other governmental agencies, spillresponse companies, and any additional entity having unwanted,uncontaminated elemental mercury. Although this service is free, you arewelcome to make a tax-free donation to help defer the costs of running thisprogram.

The process involved in the program is relatively straightforward. The entityhaving the mercury makes contact with one of the main participants in theprogram (see below) to arrange for the collection of the mercury. At the time ofthe initial contact, instructions are provided for the proper packaging of thecontainer(s). These instructions include sealing the cap/lid of the container withelectrician’s tape, placing the container in a plastic ziplock bag (if possible),sealing the bag and placing it in a secondary plastic/metal container or box.Newspaper or other material should then be placed around the bagged containerof mercury to provide some shock resistance. The secondary container shouldbe closed/sealed for further protection. Thermometers and other mercury-containing devices are placed into protected and sealed containers as their sizeallows.

The container(s) of mercury are collected by one of the program participantsaccording to the specific arrangements. The movement of mercury by privateindividuals is not encouraged. Only those having the technical knowledge relatingto mercury hazards and the capability of moving the material safely are permittedto collect the containers.

During transportation of the mercury, the containers may be placed into otherstorage units (e.g. small plastic coolers) for additional safety. Vehicles used totransport the mercury contain mercury spill materials and protective glovesshould a spill occur. Vehicle/cellular phones are also available should an incident

48

occur. A Bill-of-Lading shipping paper system is used to track the shipments ofmercury from pickup to final disposition.

Primarily, the containers of mercury are brought to Bowling Green StateUniversity’s Hazardous Waste Storage Facility. The facility is located in thenorthern section of the campus, away from academic buildings and easilyaccessible by highway. The containers are placed into a separate roomspecifically designed for poisonous materials. The mercury remains in that areauntil the mercury is consolidated. Rader Environmental Services, a hazardouswaste management company, consolidates the mercury into lead casks. Theconsolidation takes place under a working fume hood within the facility. Shouldthere be a need for consolidation in other locations not having a working fumehood, the consolidation is performed using a clean five-gallon plastic pailcontaining dry ice. The dry ice is used to minimize the release of mercury vaporsduring the transfer. The individual transferring the mercury also uses personalprotective equipment, including a respirator.

As often as necessary, the casks of mercury are transported using a regulatedtransport vehicle to Environmental Recycling, Inc. of Bowling Green, Ohio.Environmental Recycling then retorts the mercury as the initial portion of theirrecycling efforts. Bills of Lading are used during the transport and Certificates ofRecycling are obtained for the mercury sent for reclamation.

Since the program began, over 4,000 pounds of mercury have been removedfrom a variety of sources throughout Ohio as well as from locations in southernMichigan, eastern Indiana, and western Pennsylvania. Other counties inNorthwest Ohio (Allen, Erie, Henry, Huron, Ottawa, Paulding, Defiance, Mercer,and Williams) have also established cooperative mercury collection programs.We are also assisting the Ohio EPA Pollution Prevention Unit in helping hospitalsand other medical care facilities with pollution prevention programs. We areacting as a resource for removal of elemental mercury from those facilities.

Participants in the program will continue to provide information on the potentialhazards associated with elemental mercury through news releases, formalpresentations, and other feasible means.

It is hoped that others will take advantage of this valuable program and we willsucceed in reducing the amount of mercury in locations where it is notnecessary.

It is up to individual citizens, academic institutions, medical facilities, industries,and others to make the determination to take advantage of this most importantprogram. In doing so, we decrease the risk of spills and the potential ofunnecessary personal and environmental contamination.

Local Governments ReimbursementAdapted from www.epa.gov/superfund/programs/er/lgr

MISSIONEPA'S Local Governments Reimbursement (LGR) program provides Federal funds to localgovernments for costs related to temporary emergency measures conducted in response toreleases or threatened releases of hazardous substances. The program serves as a "safety net"to provide supplemental funding to local governments that do not have funds available to pay forthese response actions. Eligible local governments may submit applications to EPA forreimbursement of up to $25,000 per incident.

On February 18, 1998, EPA published a new LGR regulation that simplifies and streamlines theprocess for applicants. EPA has designed the reimbursement process to be very straightforward.Local governments obtain and complete a simple LGR application form, that requires a localgovernment to provide basic information about the incident, document its response costs byattaching copies of receipts, and certify that certain program requirements have been met. Anapplicant may receive a reimbursement check from the federal government in as little as two tothree months after EPA's receives the application. Local governments can take action today tohelp ensure that they are eligible to participate in the LGR program in the future.

EPA's LGR Program is just a telephone call away. If you have any questions about the LGRprogram and how it works, you can call the LGR Help Line at 800-431-9209 or e-mail us atlgr.epa@epa.gov.

ELIGIBILITYTo be eligible for the LGR Program, your local government must meet the following guidelines:

The applicant must be a general-purpose unit of local government. Local governments thatare eligible to receive reimbursement under the LGR program include any general-purpose unit oflocal government, such as a county, parish, city, town, township, and municipality. Federallyrecognized Indian Tribes are also eligible for reimbursement as a local government under theLGR program.

States are NOT Eligible. States are not eligible for reimbursement under the LGR program andno state may request reimbursement on the behalf of political subdivisions within the state.

The applicant must have legal jurisdiction over the site where the incident occurred. Onlyone request for reimbursement will be accepted for each hazardous substance release or threatof release requiring immediate response at the local level. When more than one local governmenthas participated in such a response, the local government that has legal jurisdiction over the sitewhere the incident occurred must submit the application. The application can be made on behalfof all participating local governments. If more than one local government or agency hasjurisdiction over the site, then the respondents must determine which single government oragency will submit the request on behalf of them all.

Reimbursement cannot be made to a responsible party. If the local government applying forreimbursement is also the responsible party, the application will be denied. Responsible partiesare liable for response cost regardless of whether or not they are a local government.

Substances released must be designated as hazardous under CERCLA. Incidents involvingpetroleum products including petroleum, natural gas, crude oil, or any other specified fractionsthereof that are not specifically designated as CERCLA hazardous substances do not qualifyunder this program. Mixtures of hazardous waste and petroleum, and in some cases petroleumwaste, may be allowable.

Maintain Your EligibilityTo ensure that the local government is best prepared to meet the application requirements oncean emergency response occurs, the local government should consider the following:

• Assign an LGR Coordinator. Identify a person to coordinate thereimbursement process. This person will be responsible for meeting theprogram's requirements throughout the response and the applicationprocess.

• Know the Program. Before an incident occurs, obtain a copy of the LGRapplication package, which includes a copy of the application and a copyof the LGR regulations. Have the application on hand and be familiar withits contents in order to facilitate the application process.

REQUIREMENTSOnce a local government has decided that it is eligible to apply for reimbursement, there are anumber of basic requirements that must be met to comply with the regulations for the LGRprogram. When completing the LGR application, local governments should pay special attentionto the following requirements to facilitate reimbursement:

Reimbursement cannot supplant local funds normally provided for a response. In otherwords, if a local government budgets for emergency response activities, it must draw from thisbudget to pay for the cost of a response. However, if a local government's funds have beendepleted, then it may be eligible for reimbursement under EPA's LGR program. In addition, otheritems that may not be budgeted for (e.g., overtime pay, unanticipated materials and supplies)may also be reimbursable under the LGR program.

Cost recovery must be pursued prior to applying for reimbursement. The applicant mustcomplete the Cost Recovery Summary Table, included in the application, to documents thebackground and current status of cost recovery efforts. It should be clear that all availablesources of cost recovery (i.e., responsible parties and their insurance, the state and localgovernment insurance) have been or are being pursued. Although not required, it isrecommended that a copy of all related correspondence also be included in the application todocument the applicant's cost recovery efforts. Potential cost recovery sources should be given aminimum of 60 days to respond before an LGR application is filed. The LGR program is self-certifying, so a local government is not required to provide extensive documentation of its costrecovery efforts. By signing on the last page of the application, a local government is certifyingthat cost recovery was pursued according to the program requirements.

Detailed cost documentation must be submitted with the application. The applicant mustcomplete the detailed Cost Breakdown Table, included in the application. All costs for whichreimbursement is being requested must be listed and supporting documentation (e.g., invoices,sales receipts, or rental agreements) must be attached. Please note: Costs incurred for long-termremedial measures do not qualify under the LGR program. Reimbursement is made only fortemporary emergency measures conducted in response to hazardous substance releaseincidents.

The local government’s highest-ranking official must sign the application. Examples of thehighest ranking official include: Mayor, Head of Town Council, or head of a federally recognizedIndian Tribe. In instances where the highest-ranking local official is unable to sign the applicationform, they must send a letter of delegation along with the application that authorizes a delegate tosign the application on his or her behalf.

51

Applications must be received by EPA within one year of the "date of completion" of theresponse, For the LGR program, the date of completion is the date when all field work has beencompleted and all project deliverables (e.g., lab results, technical expert reports, or invoices) havebeen received by the local government. The date of completion is not determined by costrecovery efforts, which can continue after an application for reimbursement is submitted. Ingeneral, a local government should allow at least 60 days for each potential source ofreimbursement to respond to a request for repayment before submitting an application to LGR.EPA will consider late applications on a case-by-case basis.

Only one request for reimbursement will be accepted for each hazardous substance releaseor threat of release requiring immediate response at the local level. When more than one localgovernment has participated in a response, the local government that has legal jurisdiction overthe site where the incident occurred must submit the application. The application can besubmitted on behalf of all participating local governments. If more than one local government oragency has jurisdiction over the site, then the respondents must determine which localgovernment will submit the request on behalf of them all.
